[Info-vax] Using MSA$UTIL to online maintain logical disk units?

[Rod Regier]

I did learn how to create a populated JBOD volume via hot plug with no reboots.

* Blank drive or re-purposed drive that has been front or full-surface zeroed.

* Hot insert the drive into a slot linked to the RAID controller

Something like this:

$SET PROC/PRIV=ALL
$MCR MSA$UTIL             ! or SAS$UTIL depending on HW
MSA> SET CONTROLLER        !selects first valid RAID controller
MSA> SCAN ALL
MSA> SHOW UNIT             ! confirm existing highwater UNIT in use
                             and ref'd DISKs
MSA> SHO DISK              ! You should see you new DISK not ref'd by UNITs
MSA> ADD UNIT # /JBOD/DISK=###  ! new UNIT
MSA> SCAN ALL
MSA> SHO UNIT              ! You should see your new UNIT
MSA> EXIT
$MCR SYSMAN
SYSMAN> IO AUTOCONFIGURE    !Get OS to re-examine RAID UNITS and assign any                            
                            missing to DQ drives.
SYSMAN> EXIT
$SHO DEV DK                 !Your new JBOD should be present but unmounted

Create content on your JBOD.  I like to create a JBOD as a separate FTP
recovery volume.

If you want to make bootable:

$DISMOUNT DKC1:
$MOU/OVER=IDENT DKC1:
$SET VOL/IDENT=newvalue DKC1:
